Sixteenth Basket of Mantaos

Imagine being forced to live, after death, as incorporeal bodies trapped in a vast space of nothingness for thousands of years, with nothing to do but exchanging past memories with other cohabitants (read: weirdos).  Everybody wanted out, but there was no way to leave the Void... 
Until one day, a young man was finally summoned, as a powerful but reluctant mentor, by a bubbly and motivated but completely naive young girl. Baiyi, finally out of the Void, was the only one who could save all of the other 32 souls from their prison and his summoner might just be The Key to their freedom.
However, Baiyi had to use the techniques and abilities the other souls had taught him throughout the years, and together with his own extensive knowledge of anime and game tropes from his shady and dangerous past as an otaku, to face the biggest challenge of them all: training the clumsy young girl he was forced to partner up with… into a competent sorcerer!

Why Did You Summon Me？

"Would you… Would you like to have a go at it with me?" Aya asked, her voice brimming with anticipation. She added, in a more hushed tone, "Y-you know, for the benefits of the students' understanding…"

"Sure!" Baiyi's answered before his mind even had time to consider the offer completely. He had never seen something like this, even from the Voidwalkers' memories, so he was driven by his own curiosity. He even summoned his students to watch the upcoming game.

"Shall… Shall we just use this amount of force and frequency?" Aya found herself feeling even bashful and embarrassed, and her expression matched her students' excitement. She held Baiyi's gauntlet softly. Strangely, as she showed him the designated frequency, her heart began to beat faster.
